TIVATOR SHARES OR SHOVELS.

SPECIFICATION formingpart of Letters Patent No. 677,694, dated July 2,1901.

Original application filed October 9,1900, Serial No. 32,510.

' vator Shares or Shovels, of which the following is a specification.

This invention relates to certain new and useful improvements instandards adapted for use in connection with cultivator shares orshovels; and one object thereof is to provide a new and improvedstandard of the character described by means of which the share orshovel is rigidly supported against strain produced by the draft of thecultivator or the encountering of roots or other obstructions,furthermore constructing the standard in such a manner as 'to strengthenthe same, and in its attachment to the cultivator.

To this end a further object of the invention is to construct a standardfor cultivator shares or shovels which shall be extremely simple in itsconstruction, strong, durable, and efficient in the use, andcomparatively inexpensive to manufacture; and it consists of the novelcombination and arrangement of parts hereinafter more specificallydescribed, illustrated in the accompanying drawings, and particularlypointed out in the claims hereunto appended.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, whereinlike numerals of reference indicate corresponding parts throughout theseveral views, and in which Figure 1 is a perspective view of thestandard, showing the share or shovel in dotted lines. Fig. 2 is avertical central section of the same. Fig. 3 is a transverse sectiontaken on the line X of Fig. 2. Fig. 4 is a transverse View taken on theline Y Y, Fig. 1. Fig. 5 issimilar view taken on the line Z Z, Fig. 1.

The subject-matter of this application is a division of the applicationfiled October 9, 1900, Serial No. 32,510.

Referring to the drawings by reference-numerals, the share or shovel lis indicated in dotted lines as mounted in position upon the Divided andthis application filed December 26, 1900. Serial (No model.)

standard. The latter is perfectly-square in cross-section near its lowerend,- and from a suitable point near its center, as 2, it is grooved orconcaved on each of its four sides, as at 3, the groove or concavityincreasing from the point 4:.up to the upper end of the standard. Thisconstruction results in the formation of four ribs 5 at each of the fourcorners of the standard, said ribs having curved sides, as most clearlyshown in Fig. 3 of the drawings. An annular flange or collar 6 is formedon the upper end of the standard, the ribs 5 at their upper endsgradually merging into said collar and being flush with 'the peripheryof the latter.

The extreme upper end of the standard is threaded, as shown, and anannular groove 8 is formed on the upper face of the collar 6,immediately adjacent to the base of the round tenon 7. By forming thesquare standard with grooved or concaved sides, as shown, or with thecurved ribs 5 the standard is greatly strengthened and at the same timemay be made light, while said ribs also form a support for and addstrength to the collar 6. The round tenon 7 0f the standard is designedto be passed through a perforation or bolthole in a metallic plate orcross-bar attached to the cultivator-beam, as shown and described inLetters Patent granted to me, No. 626,562, the collar 6 abuttingthe bossformed on the under side of said plate or cross-bar and a nut beingscrewed over the upper end of the threaded tenon above the plate orcross-bar and operating to hold the standard firmly and tightly inplace. By grooving the upper side of the collar 6, as shown, said collarbears at its outer edge against the boss, thereby afiording a strongerand more secure bearing for the collar than it would have if its upperside were made perfectly planeor straight.

In practice when a plurality of shovels are employed in each cultivatorthe standards will be made of difierent lengths, the longer shorterstandards at the rear. The forwardlyextending curved lower end, and onthe front side of which the share or shovel is secured. to the standard,is concave, as shown at 9,

reduced and rounded, as at 7, and is screw standards being arranged infront and the the concavity or curvature being greater than thecorresponding convexity of the under side of the plowshare or shovel,and said front edge of the standard is vertically or longitudinallygrooved or recessed, as at 10, whereby four bearing-points are provided,on which the under side of the plowshare or shovel rests or issupported. A single bolt-hole 11 is formed in the plowshare or shovel,as indicated in dotted lines, and a corresponding bolt-hole is formed inthe standard.

the bolt seating itself in the opening flush with the upper face of theshare, and a nut Q 13 is screwed over the opposite end of the bolt andoperates to firmly and tightly draw the the bearing 16 on the left ofthe s'tandardbelow the bolt-h ole is lower than the correspondingbearing 17 on the right. projections 16 and 17, as shown, are formed atthe extreme lower end of the standard and at the extreme outer edgesthereof. When the nut is tightened up, the share will be firmly drawn toand seated on the bearings,

the unequal heights of the latter causing the share to accurately seatitself on the bearings,

wheroit will be securely and rigidly held against movement ordisplace'mentin anydirection.

It will be evident that when a left-hand share or shovel is employed therelative heights of the bearing-points will be reversed.

It is thought that the many advantages derived from my improvedstandards for firmly and rigidly holding and supporting the shareorshovelinpositionandalsofromthestrengthening of the standard byconstructing the same in the manner shown can be readily understood fromthe foregoing description, taken in connection with the accompanyingdrawings, and it will be noted that minor changes A headed bolt 12 ispassed through said bolt=holes, the head of.

The bearings or may be made in the details of construction withoutdeparting from the general spirit of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, isp 1. A standard for cultivatorshares or shovels, comprising a bar of suitable material longitudinallygrooved or recessed and concaved on its forwardly-projecting lower end,a series of bearings or seats formed by said concavity, and means forsecuring said share .or shovel upon said bearings or seats.

7 2. A standard for cultivator shares or shovels, comprising a bar ofsuitable material longitudinally grooved or recessed and concaved on itsforwardly-projecting lower end, a series of bearings or seats of unequalheight formed by said concavity, and means for securing the share orshovel upon said bearings or seats. I

3. A standard for cultivator shares or shovels, comprising a metallicbar square or rectangular in cross-section at its lower end and fromthence grooved or coucaved on its four sides, said grooves orconeavities increasing in depth from their lower ends to the upper endof the standard, substantially as described. I

4. A standard for cultivator shares or shovels, comprising a metallicbar provided with a round and threaded tenon at its upper end and withan annular flange or collar below said tenon, said flange or collarbeing provided on its upperside with an annular groove immediatelyadjacent to the base of the te'non,

the standard being square or rectangular in cross-section at its lowerend and from thence grooved or concaved on its four sides upward tothe-collar, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
